  • Patent number: 11213241
    Abstract: A method for QT correction is provided, the method comprising receiving an ECG signal; extracting a plurality of beat-to-beat (RR) intervals; extracting a plurality of QT intervals; computing a first probability distribution for a range of QT values based on the plurality of QT intervals; computing a second probability distribution for a range of QT values based on the plurality of QT intervals and the plurality of RR intervals; solving one or more points, wherein the first probability distribution and the second probability distribution intersect or wherein a difference between the first probability distribution and the second probability distribution is below a pre-defined difference threshold; designating one of one or more QT values corresponding to the one or more points as a corrected QT interval for a given QT interval of the plurality of QT intervals.

  • Patent number: 6449872
    Abstract: The invention relates to a heat treatment method of cereal kernels which enables the decrease in the mould content of the cereal kernels without disturbing their germinability. The method is especially applicable to the treatment of kernels to be germinated e.g. before malting. The invention also relates to the treated cereal kernels, cereal kernel products made of them and their use in malting and brewing. Further, apparatuses are described which are applicable to the heat treatment of cereal kernels.
